It also fits the IP1250 and IP1251 models. Swap it in when the original cell no longer holds a usable charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIP3000 and POWERDETECT platform fit:\u003c\/strong\u003e\n    These models share the same 21.6V battery rail, connector pinout, and BMS handshake protocol. One cell covers the full group — no adapter needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on an IP3000 unit. The BMS accepted the handshake immediately, the vacuum powered on without error codes, and charge termination triggered correctly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on cordless vacs:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock between uses. Continuous trickle charging accelerates capacity fade in lithium cells. Charge to full, then remove it from the dock until the next use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor is drawing more current than the BMS expects under normal load — usually caused by a partially blocked filter or brush roll restriction. The BMS reads the elevated draw as a low-voltage event and throttles power to protect the cell. The motor doesn't cut out completely; it just loses torque and the vacuum feels weak. Clean the filter and check the brush roll for hair wrap before concluding the battery is the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-use and then recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip — the motor hits a sustained high-draw event, the BMS opens the discharge circuit to protect the cell, and the vacuum dies. After 20–30 seconds the BMS resets and the unit powers back on. It typically occurs when suction is restricted: a clogged filter forces the motor to work harder, current climbs above the BMS trip threshold, and the cutoff fires. Clear the filter, check for blockages in the wand or base, and confirm the battery resting voltage is above 21V before ruling out cell degradation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426462957658,"sku":"BWCS-SHP300VX-1","price":98.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43426462990426,"sku":"BWCS-SHP300VX-2","price":116.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43426463023194,"sku":"BWCS-SHP300VX-3","price":129.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHP300VX-1.webp?v=1779933315","url":"https:\/\/batteryweb.com\/products\/shark-ip3000-replacement-battery-216v-3750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
